Innovation in Fish Nutrition, Production Technology, and Welfare

Dear Colleagues,

Aquaculture is a continuously expanding sector that developed due to the need to provide sustainable food for a growing population and to counterbalance the decline of the fish population in the wild. At the same time, aquaculture is a source of income and food for farmers in less developed countries. To ensure the high demand for products and profitability, the cultivation densities were greatly increased, an aspect that brings numerous challenges and problems. Among these, the most frequent are the problems related to water quality degradation, the occurrence of physiological stress, and decreased animal welfare. At the same time, the COVID-19 pandemic and the increase in energy prices caused an increase in feed prices, which represent over 50% of the production cost, putting farmers in a difficult situation. Scientific and technological development can contribute to solving these problems by developing more efficient growing systems with reduced environmental impact, making feed from new and sustainable ingredients with a higher conversion factor, and developing natural products to fight diseases and parasites. This Special Issue is dedicated to interdisciplinary studies on fish nutrition, physiology, chemistry, biochemistry, genetics, reproduction, and breeding technologies. The articles will cover a wide range of topics related to water quality, feed quality, the influence of diets on production levels, the quality of production, and fish welfare.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Life is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs).
